What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is taken out and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom layout, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the work involves rerouting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then constructing the new shower floor with a code-compliant slope toward the drain. New waterproof liner is applied before any finish material goes on. Plumbing is adjusted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you select.
The result is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done right is not just a surface-level change — it is a thorough improvement to your bathroom's structure and usability.
Top Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower restores that square footage to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a low-threshold or curbless entry, grab bars, and a built-in seat to accommodate homeowners with limited mobility.
- Quicker Showers — Most people shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Better Return on Investment — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to real estate agents.
- Easier Cleaning — Shower pans, walls, and glass enclosures are generally easier to clean and maintain than a standard bathtub with hard-to-reach corners.
- Custom Design Options — From natural stone slabs to frameless glass doors, a tub to shower conversion unlocks significantly broader design directions than a one-piece tub unit.
- Water Efficiency — Soaking in a tub consumes roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Long-Term Durability — When our crew installs a tub to shower conversion, the structural components are designed for durability well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A remodeling specialist meets with you on-site to measure your existing space and infrastructure. We go over your wishlist and timeline so the project plan matches exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are demolished and cleared. Any plumbing connections tied to the old tub are professionally handled to make room for the updated fixture configuration.
- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a continuous waterproof layer is applied across every area that will contact water. The floor base is pitched properly to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew set the new rough-in plumbing according to your fixture selections. Whether you selected a basic or premium shower setup, everything is roughed in at this point.
- Tile, Stone, or Panel Installation — Tile setters install your selected finish material using the correct adhesive and grout system. Every grout joint is finished and checked before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we install your chosen enclosure system. Every mounting bracket is secured correctly to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we conduct a room-by-room final inspection. All caulk joints at corners and the floor-to-wall transition are caulked with flexible waterproof sealant. We walk you through the completed project and confirm everything meets your expectations.
Who Is a Good Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are usually perfect for a tub to shower conversion. This also applies to homeowners who struggle with high tub walls — a barrier-free shower conversion is one of the most impactful accessibility upgrades you can make to your bathroom. Parents of toddlers who previously needed the tub for baths may want to reconsider timing once the kids are past the bathtub stage.
A tub to shower conversion also makes sense for people dealing with a cramped layout where the tub consumes the room layout. Removing the tub and replacing it with a right-sized walk-in shower can make a small bathroom feel significantly larger. Keep in mind, if your home only has one bathroom, keeping at least one bathtub is something to weigh carefully before scheduling demolition.
Those who see the greatest return from a tub to shower conversion are those committed to a bathroom that works for years ahead as well as those preparing to sell and needing a bathroom that reads modern and updated. Our crew at our firm will give you a straight answer if a tub to shower conversion is not the best call for your home.
